The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Gunnar
warrior, fighter — literally 'battle-army'
From Old Norse Gunnarr, combining gunnr 'battle, war' with the element -arr, from herr 'army, warrior'.
Gundahar (Old High German) → Gunnarr (Old Norse) → Gunnar
How it traveled
Gunnar comes from Old Norse Gunnarr, a compound of gunnr, 'battle', and an element meaning 'army' or 'warrior' — the same Germanic pair that produced Gunther further south. It belongs to the oldest layer of Norse naming and turns up in the great medieval texts: Gunnarr of Hlíðarendi is the doomed hero of Njáls saga, written in Iceland in the thirteenth century, and Gunnarr appears in the legendary poems of the Poetic Edda as the brother of Gudrún.
Gustavo
most often read as "staff of the Goths"
Two serious readings compete for the Old Norse original. One takes it from the elements Gautr, meaning a Goth, and stafr, a staff or support. The other traces it back to the Slavic name Gostislav, built from words for guest and glory. Neither has won the argument, and the name is older than the records that would settle it.
Gautstafr → Gustav → Gustavus → Gustave → Gustavo
How it traveled
The oldest form is Scandinavian — Gustav, a Swedish royal name from the sixteenth century, Latinized for European chanceries and battlefield dispatches as Gustavus. That Latin form is what traveled: it gave French Gustave, German and Swedish Gustav, and, in the Romance languages, Gustavo.

Out loud, and in short
Gunnar
GUN-ar
Stress on the first syllable. In Norwegian and Swedish the first vowel is closer to 'goo' and the double n is held longer: GOON-nar.
- Gunn — The usual clipped form; also stands alone as a given name in Norway, where it is used for women.
- Gunny — Informal, family-level; also long-standing US military slang for a gunnery sergeant.
- Gunni — Informal short form used in Iceland and Denmark.
Gustavo
goo-STAH-voh
Three syllables in Spanish and Portuguese, stress in the middle. English speakers sometimes shift it to guh-STAH-voh, which passes without trouble; the version to correct early is GUS-tuh-voh, with the weight on the front.
- Tavo — The standard informal short form across Spanish-speaking families; used among friends and relatives rather than on paperwork.
- Gus — The usual English-language shortening; also stands alone as a given name in its own right.
- Tavito — Spanish diminutive of Tavo, mostly used for children and by older relatives.
- Guty — An affectionate Latin American short form, informal only.

The trade-offs, name by name
Gunnar
Strengths
- Spelled and said the same way in Norwegian, Swedish, Danish and Icelandic — it crosses those borders without adjustment.
- Two syllables, phonetic spelling, one obvious stress pattern; almost no one will need it repeated.
- A documented record going back to Old Norse and the thirteenth-century Icelandic sagas, with no gap where it fell out of use.
To consider
- Gunner — the occupational word and a separate American name — sounds nearly identical, so expect that spelling to come back at you on forms, mail and rosters for life.
- The first syllable reads as 'gun' in English, and the meaning is frankly martial. Some families like that plainly; others find the firearm echo, and the nickname Gunny, more than they want.
- Outside families with Nordic ties, people may not immediately recognize it as an old name rather than a modern coinage — which is easy to correct, and the correction is a good story.
Gustavo
Strengths
- One spelling in Spanish, Portuguese and Italian, so it crosses borders without being rewritten or re-explained.
- Documented since the sixteenth century in its northern form and continuously on US records since the early twentieth.
- Ready-made short forms at both ends: Tavo in Spanish, Gus in English, neither of them invented on the spot.
To consider
- Outside Spanish- and Portuguese-speaking circles, some people will default to the stress pattern of Gustav and land on GUS-tuh-voh. It is an easy correction, but one you make more than once.
- The name places a child clearly in a Hispanic and Latin American naming tradition. For many families that is exactly the point; it is worth knowing it reads that way to strangers.
- Gus, the English short form, has an older and more Anglo history of its own, so a Gustavo may find himself handed a nickname with a rather different flavor than the full name.
